Jo

Doctor Who Episode Guide | Companions | Jo

Jo Grant, portrayed by Katy Manning, was a companion of the Third Doctor. She first appears in Terror of the Autons as a replacement assistant for the Doctor.


Josephine “Jo” Grant had only just completed a brief training period as a spy when she had her uncle use his influence to assign her to UNIT. As the Doctor’s assistant, Jo’s knack for getting into trouble was immediately apparent.

Ditzy, but fiercely independent, Jo’s confidence and bravery grew with experience. As well as facing a series of adventures on Earth, during the Doctor’s exile, she also visited a number of alien planets, including Skaro and Peladon.

After disappointing a series of would-be suitors, Jo finally fell in love with Eco-warrior Professor Clifford Jones, and left the Doctor to explore the Amazon with her new fiancé.
